Looks good, but i was looking at your electrical circuit-is it plugged into a Molex? If so i think you might have your electrical inputs mixed up. If you're using another power source, like from the Mobo, then it's allright, but the molex provides a 12v and a 5v and 2 ground, unless i'm mistaken. Which won't cause a lot of trouble, i don't think.
If i'm wrong, please correct me-cos i need to know!
